In American films, you have probably noticed more than once that the temperature is measured quite strange there. It is strange for us, because we are used to the fact that we have this indicator in degrees Celsius. At zero, the water freezes, at a hundred it boils. Everything is simple and convenient. But for a typical American, this will seem marvelous. After all, he will argue that water turns into ice at 32 degrees. But only in Fahrenheit. Of course, the temperature in Celsius and Fahrenheit will be very different. Let's see how much. Why it happened and learn how to translate Fahrenheit in Celsius.
Fahrenheit or Celsius?
All over the world it is customary to measure temperature in degrees Celsius (° C). Actually, this system is named after the Swedish scientist who in the 18th century developed a new scale. At first, he took the boiling point of water as zero, and freezing occurred at a hundred degrees. But then either he himself, or someone else (not known for certain) reviewed the system and simply turned it upside down.
Since then, this scale has become the most common in the world, displacing various analogues. But one still firmly seated. In the United States, temperature is still spoken in degrees Fahrenheit (° F). Other English-speaking countries and Europe abandoned this unit in the past century.
Fahrenheit, the water boils at 212 degrees, and freezes at 32. 100 ° F corresponds to the temperature of the human body, and from there it repelled. True, if you translate a hundred degrees Fahrenheit in Celsius, you get a little more than 37 ° C. Probably, at the time the system was created, the scientist had a fever.
Objectively, his system (also called the name of the scientist) is not very logical, compared with Celsius, but has the right to life.
How to translate Fahrenheit to Celsius?
This skill is unlikely to ever come in handy to you, but if you suddenly find yourself in the states or drive a purely American car, that's fine. To transfer from one system to another, there is a Fahrenheit to Celsius formula. It can certainly be used in the opposite direction.
For the temperature in ° F to become ° C, you need to subtract 32 from the original number, divide the difference by two and add one tenth to the resulting number.
For example, you came across an American thermometer. You measured the temperature and it was 98 degrees Fahrenheit. In Celsius this value will be as follows: 98 - 32 = 66/2 = 33 + 3.3 = 36.3 ° C. Such a calculation is quite accurate, there is, of course, a small error, but for household needs this formula is quite acceptable.
How to convert Celsius to Fahrenheit?
Pretty simple. We multiply the temperature in Celsius by 1.8 and add 32. For example, 100 ° C will be equal to 212 ° F, that is, 100 x 1.8 + 32. In general, some thermometers produce both scales on both sides, which instantly solves the issue and one does not need to think how to translate Fahrenheit in Celsius.
In addition, there are various online converters and applications on the phone, so there should be no problems.
It is worth noting that none of the above temperature measurement scales is absolute. These are household systems, but in science they use others for various studies, such as the Kelvin scale (K), for example, where zero is the lowest possible temperature at which it is unrealistic to extract thermal energy from a substance (0K = −273.15 ° C = - 459.67 ° F).
